...BIG CHANGES IN THE WEATHER COMING TO NORTHERN COLORADO TONIGHT...

Winter will make an early arrival in northern Colorado tonight and Tuesday as a strong cold front from central Canada will bring much colder temperatures as well as accumulating snow to the region. Temperatures will drop quickly behind a cold front this evening with snow starting shortly after midnight over the higher mountains and foothills. Snow levels are expected to drop through Tuesday morning, with accumulating snow expected along the Front Range, I-25 corridor, and adjacent plains. Snow falling on trees that are still in full leaf may cause branches and limbs to break, resulting in scattered power outages. Roadways could become slippery and slushy in the mountains and foothills. The weather system is expected to weaken Wednesday with snowfall coming to an end and conditions improving through the day.
